FZ/T 98004-2008Textile fiber linear density meter vibrating method (English PDF)

Foreword

The reference standard ISO 1973:1995 "Determination of linear density of textile fiber weighing method and vibration meter method" and GB/T 16256-1996 "Textile fiber linear density test method vibrometer law" test the principles and methods developed. Determine the content of the following points.

--- Tension clamp weight error;

--- Resonance frequency error;

--- Fiber test effective length (vibrating wire length) error;

--- The three basic functions of computing;

--- Working conditions of ambient temperature and relative humidity test fiber;

--- A standard sample in the instrument calibration and correction method test results Appendix.

Appendix A of this standard is an informative annex.

The standard proposed by China Textile Industry Association.

This standard by the National Standardization Technical Committee Textile machinery and accessories.

This standard was drafted. Taicang Hongda Fangyuan Electric Co., Materials Engineering, University of Suzhou, Wuxi, People's Republic of China and out Habitat Inspection and Quarantine, the State Quality Supervision and Inspection Center of silk.

1 Scope

This standard specifies the exciting type of fiber line densitometer requirements, test methods, inspection rules and signs, packaging, transportation and storage.

This standard applies to the way the fibers with exciting start-up, measuring the resonant frequency of the excitation fiber type fiber line densitometer photoelectric detection system.
